There are more than 50 determinations of wing-beat frequencies in the
literature, ranging between 110 and 330 Hz

Subject: [Syrphidae] wing speed

Hi all,

Via my website I received the following interesting question from
Israel...

"I would like to find out if it is true that the wing flight speed of a
syrphid can achieve 5 ms which means - 200 per second?"

...anyone has an answer on this? I guess there is a range.

regards,
Bastiaan
